I hope your workload will lower soon. In fact the statement "I'll file
an issue ..." is part of the citation. ;)
But I'd take that task if I am sure what to write. Is it a limit or a
lenght for:
Form.Columns.getByName("").setBinarySream()
aka ResultSet.get/setAnything.setBinaryStream()
Form.Columns.getByName("").updateBinaryStream()
aka ResultSet.get/setAnything.updateBinaryStream()
css.sdbc.XParameter.setBinaryStream()
?
And I'll try again:
Does the last of those three (or all at best) need a stream implementing
css.io.XSeekable besides the XInputStream/XOutputSream interface?
The same is true for the ComponentLoader (not Documentloader) for input
streams, which is why people have to implement a stream wrapper offering
both interfaces (XInputStream & XSeekable).
Since my experiments handing over an input stream to a XParameter are
all blocking except when a dbase db is used as backend this could be the
problem. Or the "length" argument is biting back ...
